If you are having trouble

–If you don’t see the picture you want to see, slowly press the correct input on the Extron control panel.

–if the screen is black but the projector and the source are on, press the Blank Screen button on the Extron control panel to turn off the picture mute.

–If you don’t hear anything but you are playing audio from the PC or laptop, check the computer’s volume setting by clicking on the small speaker icon in the lower right corner and raising the volume control. Check the volume control on the Extron control plate, to make sure it is turned up. If you are using a laptop, make sure that the Laptop Audio plug is pushed into the laptop’s headphone output. Loud buzzing usually means that it is plugged into the microphone jack instead.

– Because we have more sources than inputs available on the video projector, a laptop signal has to “loop” through the doc cam. The doc cam has to be turned on for the laptop’s picture to be visible.

–If you see the picture you want to see but it is a strange color like green or pink, a cable is partially plugged in. Check the cables to a laptop, the Doc Cam, and the wallplate, if there is one.

–If there are messages from the projector like Please Clean Filter, please let the Help Desk know at x7075 or help@mbc.edu.
